MT573 Dash Warning Light

TimberFarm · Sunday at 9:27 PM

I just had the dash warning light that looks like a red Exclamation Point come on along with an ear piercing warning siren. The manual just says: "Vehicle Control Error Warning Indicator" and says to contact dealer. Any ideas on what this is?
It gets triggered when I put it in gear (I have shuttle shift) and let the clutch out and start moving. It will go off if I depress the clutch pedal about 1/2".

No codes at all?

I don't have a code reader for this. I was hoping somebody else may have had this issue. Any links on code readers that are compatable with LS?

codes display on your dash on the left side. You should be able to look in your manual for the red ! point. For my tractor the exclamation point in red there's also another display associated with regen light. Maybe you exceeded your regen failures (3X) and the ECM needs to be reset by the dealer?? Usually they could come to you to fix that instead of trailering your tractor to the dealer. I've only herd of this issue.... so not positive just throwing that out there.

I agree, fault codes should show on the instrument cluster if there are any active codes. Non-active codes stored can only be retrieved with the dealer's service tool or another scanner that will work on this tractor. If this happens when letting the clutch out and starting to move, the clutch pedal maybe needs to be calibrated or a clutch pedal switch is not working correctly. I say that because you said if you push the pedal down about 1/2", the warning goes away. If the park brake switch was telling it that the park brake was on while trying to move, pushing the pedal down slightly should not matter. Also if the seat switch was not working, it would not let you try to move.

No codes displayed. Ironically I had a regen occur yesterday. Couldn't drive it due to this warning beeper going off so I just parked it and turned up the throttle. This tractor regens regularly around 50hrs. I never canceled regens. If they came up I would drive the tractor to complete the regens.
This is all the manual says about the red exclamation point: "Vehicle Control Error Warning Indicator" and says to contact dealer.
